32 bit displacement maps not working

[Luxalpa]

Hello,

I've exported my displacement maps from ZBrush. I tried using the EXR format and TIFF, however neither of them seems to be working. The material is shown as entirely black, it does not show any sort of displacement in the viewport nor iray no matter what settings I enable. The 16 bit TIFF works if I put it into the height channel.

Are 32 bit displacement maps not supported yet?
